Section 303(d) of the Clean Water Act requires states to identify waters that are impaired by pollution, even after application of pollution controls. For those waters, states must establish a total maximum daily load (TMDL) of pollutants to ensure that water quality standards can be attained. Implementation was dormant until recently, when states and EPA were prodded by numerous lawsuits. digital.library.unt.edu/ark:/67531/metacrs1524/

Exposure to certain chemicals in the environment could disrupt the hormone systems of animals and humans, according to some scientists who are concerned about potential risks to public health and ecosystems. Congress has mandated chemical screening to assess the potential of pesticides and drinking water contaminants to influence the normal functions of female, male and thyroid hormones. As conflicting scientific evidence accumluates on the hormone disruption hypothesis, legislators may consider proposals to increase or decrease funding for the endocrine disruption screening program, or to expand its requirements to include additional chemicals or hormone functions. digital.library.unt.edu/ark:/67531/metacrs1879/

Key water quality issues that may face the 107th Congress include: actions to implement existing provisions of the Clean Water Act, whether additional steps are necessary to achieve overall goals of the Act, and the appropriate federal role in guiding and paying for clean water activities. This Act is the principal law that deals with polluting activity in the nation’s lakes, rivers, and coastal waters and authorizes funds to aid construction of municipal wastewater treatment plants. Legislative prospects for comprehensively amending it have been stalled over whether and exactly how to change the law. digital.library.unt.edu/ark:/67531/metacrs2041/

In the Safe Drinking Water Act (SDWA) Amendments of 1996 (P.L. 104-182), Congress authorized a drinking water state revolving loan fund (DWSRF) program to help public water systems finance infrastructure projects needed to comply with federal drinking water regulations and to protect public health. Under the program, states receive capitalization grants to make loans to water systems for drinking water projects and certain other SDWA activities. Since the program was first funded in FY1997, Congress has provided $7.8 billion, including roughly $844 million for FY2005. The President has requested $850 million for FY2006. Through June 2004, the DWSRF program had provided $7.9 billion in assistance and had supported 6,500 projects. digital.library.unt.edu/ark:/67531/metacrs7773/

This report describes the revised environmental rules of the Clean Water Act, the background of previous Clean Water Act rules and the Clinton Administration proposal for revising these rules, and perspectives of key interest groups on the proposal and final regulations. It also identifies several issues likely to be of congressional interest as implementation of the revised rules proceeds. digital.library.unt.edu/ark:/67531/metacrs9077/

Section 303(d) of the Clean Water Act requires states to identify waters that are impaired by pollution, even after application of pollution controls. For those waters, states must establish a total maximum daily load (TMDL) of pollutants to ensure that water quality standards can be attained. Implementation of this provision has been dormant until recently, when states and EPA were prodded by numerous lawsuits. The TMDL issue has become controversial, in part because of requirements and costs now facing states to implement a 25-year-old provision of the law. Congressional activity to reauthorize the Act, a possibility in the 2nd Session of the 105th Congress, could include TMDL issues, but the direction for any such action is unclear at this time. digital.library.unt.edu/ark:/67531/metacrs10107/

In October 1997, Vice President Gore directed federal agencies to develop a Clean Water Initiative to improve and strengthen water pollution control efforts. The multiagency plan was released on Feb. 19, 1998, and identifies nearly 100 key actions. Most are existing activities, now labeled as part of the Initiative. The President's FY1999 budget requests $2.2 billion for five departments and agencies to fund implementation of the Plan. While Congress is considering appropriations bills to fund the Plan, federal agencies are beginning or accelerating activities to carry out the actions under the Plan. digital.library.unt.edu/ark:/67531/metacrs10008/

The Environmental Protection Agency is attempting to develop a regulatory response to a 2006 federal court ruling that vacated a long-standing rule that exempts discharges associated with the normal operation of vessels from permit requirements of the Clean Water Act. Concern that this ruling could require millions of recreational boaters to obtain permits has led to the introduction of legislation to exempt these and other types of vessels from water quality regulation. This report discusses background to the issue; bills introduced in response, two of which were passed by Congress on July 22; and draft permits proposed by EPA on June 17. digital.library.unt.edu/ark:/67531/metacrs10738/

With increasing concentrations of carbon dioxide (CO2) in the atmosphere, the extent of effects on the ocean and marine resources is an increasing concern. One aspect of this issue is the
ongoing process whereby seawater becomes acidified (i.e., ocean acidification) as more CO2 dissolves in it, causing hydrogen ion concentration in seawater to increase. While not yet fully
understood, the ecological and economic consequences of ocean acidification could be substantial. Congress is beginning to focus attention on better understanding ocean acidification and determining how this concern might be addressed. digital.library.unt.edu/ark:/67531/metadc26133/

The principal federal program to aid municipal wastewater treatment plant construction is authorized in the Clean Water Act (CWA). In appropriations legislation, funding for EPA (Environmental Protection Agency) wastewater assistance is contained in the measure providing funds for the Department of the Interior, Environment, and Related Agencies. This report summarizes, in chronological order, congressional activity to fund items in the State and Tribal Assistance Grants (STAG) account since 1987. digital.library.unt.edu/ark:/67531/metadc26111/

Section 401 of the Clean Water Act requires that an applicant for a federal license or permit provide a certification that any discharges from the facility will comply with the Act, including water quality standard requirements. Disputes have arisen over the states' exercise of authority under Section 401. Until recently, much of the debate over the Section 401 certification issue has been between states and hydropower interests. A 1994 Supreme Court decision which upheld the states' authority in this area dismayed development and hydroelectric power interest groups. The Court revisited these issues in a 2006 ruling that unanimously upheld the states' authority to condition hydropower licenses. The dispute between states and industry groups about Section 401 authority has been a legislative issue on several occasions, but Congress has not responded by modifying the provision's scope. In addition, there has been interest in clarifying whether Section 401 certification applies to nonpoint source discharges, such as rainfall runoff, as well as point source discharges from pipes or ditches. digital.library.unt.edu/ark:/67531/metadc83833/

This report discusses the water quality issues. Although much progress has been made in achieving the ambitious goals that Congress established more than 35 years ago to restore and maintain the chemical, physical, and biological integrity of the nation's waters, long-standing problems persist, and new problems have emerged. digital.library.unt.edu/ark:/67531/metadc86536/

This report describes the several types of waste streams that cruise ships may discharge and emit. It identifies the complex body of international and domestic laws that address pollution from cruise ships. It then describes federal and state legislative activity concerning cruise ships in Alaskan waters and activities in a few other states, as well as current industry initiatives to manage cruise ship pollution. digital.library.unt.edu/ark:/67531/metadc87283/

This report discusses the Clean Water Act that contains two different permitting regimes: (1) Section 402 permits (called the National Pollutant Discharge Elimination System, or NPDES, permit program) address the discharge of most pollutants, and (2) Section 404 permits address the discharge of dredged or fill material into navigable waters of the United States at specified sites. These permit programs differ in nature and approach. digital.library.unt.edu/ark:/67531/metadc87257/
